y 1936. 1.. J. SCHMIDT' KEEPER PROTECTIVE PLATE Filed June 4, 1935INVENTOR I BY W 7% A TORNEY WITNESS Patented May 19, 1936 UNITED STATESPATENT OFFICE KEEPER PROTECTIVE PLATE Louis J. Schmidt,

Application June 4,

2 Claims.

The invention relates to a locking device and more especially torefinements over the subject matter of United States Letters Patent No.1,878,544 issued September 20, 1932.

The primary object of the invention is the provision of a device of thischaracter, wherein the keeper slot for a latch or look will be protectedto prevent the chewing away or mutilation of the wall of the slot whenoperating the lock or latch.

Another object of the invention is the provision of a device of thischaracter, wherein the protecting member can be fastened in place withinthe keeper slot without the use of nails or separate fasteners, theprotecting plate being novel in construction and is applied withdispatch and when in place will be firm and secure.

A further object of the invention is the provision of a device of thischaracter, which is extremely simple in construction, reliable andefficient in its purpose, strong, durable, easy of application andinexpensive to manufacture.

With these and other objects in View, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawing, which discloses the preferred embodiment of the invention andpointed out in the claims hereunto appended.

In the accompanying drawing:

Figure l is a fragmentary elevation of a locking device forming thesubject matter of United States Letters Patent No. 1,878,544 datedSeptember 20, 1932, with the protection plate constructed in accordancewith the invention in association.

Figure 2 is a horizontal sectional view thereof.

Figure 3 is a perspective view of the protection plate.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, I indicates a closure or the likeassociated with a frame 2 grooved or slotted to provide a keeper 3 inwhich the locking element 4 is moved to secure the closure againstrelative movement with respect to the frame 2. The closure I is providedwith a seat or recess 5 adapted to align with the keeper 3 and haspositioned therein a cup or casing 6 provided with a bottom wall 1 andintegral side wall 8 provided with an attaching flange 9 apertured toreceive suitable fasteners for firmly attaching the cup or casing to theclosure I. The latch element 4 comprises an elongated head In havingrounded or arcuate shaped ends II and substantially straight sides l2that the latch element may rotate freely within the cup or casing ineither direction. A handle I3 is formed on one of the straight sides l2of the head and is offset to extend outwardly of the cup or casing 5Fond du Lac, Wis.

over the flange 9 to permit a person to easily obtain a firm grip on thehandle for moving the head into and out of engagement with the keeper 3and the offset provides a very suitable leverage for facilitating theactuation of the device. This locking device is disclosed in UnitedStates Letters Patent No. 1,878,544 issued September 20, 1932.

Cooperating with the latch element 4 is a protection plate whichconstitutes refinements over the subject matter of the Letters Patentaforesaid and comprises an L-shaped metal piece l4, the flange portion15 of which has the substantially arched edge I 6 corresponding to thebottom I! of the keeper 3 while the flange portion l8 has the roundedends l9 and upon these portions are formed pointed arrow-shaped prongs20 and 2|, respectively, which function to secure the protection platein place and with the part to which it is attached.

The prongs 2| are bent at right angles to the plane of the portion I8while the prongs 20 are in 'the same plane with the portion I5.

In the use of the protection plate the same is placed with respect tothe keeper 3 so that the portion [5 will lie against the striking wallof the keeper with the prongs penetrating the frame 2 while the portionI8 is at the meeting edge of said frame with relation to the closure Iso that when the latch element 4 is engaged in the keeper 3 it will playagainst the protection plate to avoid mutilation of the frame 2 and thechewing away of the wall or walls of the keeper 3 when the closure l islatched. The portion 18 lies against the edge of the frame 2 nextto theclosure I.

What is claimed is:

1. A protector plate for the walls of a mortice in a wooden abutmentthat provides a keeper opening for a latching device on a member whichis swingable against the face of the abutment, said 40 protector platecomprising a substantially ,L- shaped member, and securing prongsintegrally formed with said member and having pointed free ends, theprongs being in parallel relation to each other and disposed in the samedirection with respect to one another.

2. A protective plate for a mortice in a wooden structure, in which saidmortice provides a keeper for a latching device, said protective platecomprising a substantially L-shaped member, and securing prongsintegrally formed with said member and having pointed free ends, theprongs being in parallel relation to each other and disposed in the samedirection with respect to one another, the member being insertable inthe mortice to have one portion cover one wall of said mortice and theother portion overlying the edge next to said wall of the mortice.
